Abstract

A material testing machine comprises an indenter (32) for making an indentation in a specimen (1) and detection means (61;81) for detecting the indentation pressure and amount of penetration. An elastic member is interposed between an indenter pressing member (25) and the indenter (32). A displacement detector (61,81), having a stator (61a,81a) and a movable element (61b,81b) coupled to the indenter (32) and the pressing member (25), detects the amount of compression of the elastic member. A pulse counter counts a train of pulses generated in response to movement of the pressing member (25).
